Benefit

Independently certified IEC 60529 usage in even the most demanding conditions.

Measuring where no other laser tracker can go. The controller stays out of the user’s way, e.g. attached to the tripod.

By combining built in WiFi connectivity and on board battery power, the sensor can operate without any wires connected at all.

No need to worry about AC (mains) power – the sensor can run continuously with a new set of batteries able to be swapped in without interruption

The ATR allows constant tracking and fine positioning with different reflector types to a typical radial volume of 320 m.

No need to worry about “breaking the beam”: the tracker automatically locks onto the user providing up to 20% time savings over traditional laser tracker technologies

The most accurate Leica Geosystems distance meter ever: The ADM has a resolution of 0.1 micron and a maximum uncertainty of 10 microns over a full 160 m radial volume.

A built in “survey grade” level to gravity sensor is combined with a simple three screw leveling quick release platform for quick and easy machine setup and relocation.

Integrated Overview Camera to allow on-line steering of the laser tracker for remote or fixed installations

Automatic reading and updating of the environmental param-eters avoids inaccurate calculations or wrongly input values.

The absolute angle encoders provide traceable ISO 17123-3 0.5” accuracy with a 0.07” resolution guaranteeing system accuracy over extremely long ranges.

Due to its low power requirements the sensor can use POE+

technology that combines power and data into a single off the shelf Cat5 LAN cable.
